Pyridoxine-d5

Description:

Pyridoxine-d5, also known as deuterated pyridoxine, is a stable isotope-labeled form of pyridoxine, which is commonly known as vitamin B6. The "d5" designation indicates that five hydrogen atoms in the molecule have been replaced with deuterium, a heavier isotope of hydrogen. This modification allows for enhanced tracking and analysis in various biochemical studies, particularly in metabolic research and pharmacokinetics. Pyridoxine itself is a water-soluble vitamin that plays a crucial role in amino acid metabolism, neurotransmitter synthesis, and the production of hemoglobin. The deuterated form retains the same chemical properties as the non-deuterated version but can be distinguished in analytical techniques such as mass spectrometry. Pyridoxine-d5 is utilized in research settings to study vitamin B6 metabolism and its effects on human health, as well as in the development of pharmaceuticals. Its CAS number, 688302-31-0, is a unique identifier that facilitates its recognition in scientific literature and databases.

Pyridoxine-d5 (major)

CAS: 688302-31-0

Pyridoxine-5-d5 is a vitamin that belongs to the group of pyridoxines. It is an essential cofactor for enzymes in amino acid metabolism and the biosynthesis of neurotransmitters, hormones, and other compounds. Pyridoxine-5-d5 has been labeled with deuterium oxide (D2O) to form pyridoxine-d5. This compound can be analyzed using mass spectroscopy and ionization mass spectrometry. The chemical structure of pyridoxine-d5 can be obtained by acetylation or deuteration as well as by deuterium incorporation.
